Abstract
A navigation device is provided, which at a junction such as an intersection point, and the like, offers to a driver an appropriate image of the vicinity of the junction which is required in turning right or left, and the like.
A route search section (102) searches for a route leading to a set destination. An imaging regulation setting section (107) determines an imaging regulation of an imaging section (109) at a junction which exists on the searched route. A distance calculation section (104) calculates a distance between a position of a vehicle and the junction. A control section (108) changes an image to be shown in an output device according to the calculated distance based on the determined imaging regulation.
